NEWTOWN SQUARE–On Saturday, June 9, Marple Newtown High School senior Wil Kauffman finally took "his girl" to prom, which was held at Drexelbrook Banquet Facilities.

On March 9, Kauffman performed a surprise prom proposal with 10 of his buddies to his girlfriend Megan Weinberg during Julie McFarlane's first period AP Physics class.

Kauffman wore a pair of sunglasses and sang "My Girl" in a capella style with his 10 friends. Kauffman–with flowers in hand–dropped down to one knee and asked Weinberg to prom. Her obvious answer: "yes."

Kauffman's YouTube prom proposal video went viral, tipping off local radio station Philly's B101 who interviewed Kauffman about the surprise proposal.
